I'm really struggling with this problem.

f-Distribution Professor Bond claims her mean test score is a 80 - but you worry it's lower than that. Arca in Right Tail 0.25 0.20 0.05 0.025 0.02 0.005 0.0125 0.001 0.0005 To test Ho: J = 80 versus He : 30. 1.100 1.383 2.262 2 398 2.821 4.781 3.581 O C. No, because n> 30. 11 0.697 1.058 1.363 2.201 2 328 3.497 4.025 4.437 11 O D. No, because the test is two-tailed. 0.695 2.179 2 303 3.055 3.428 3.930 4.318 4.221 0.692 1076 1.76 2.145 2.624 3.326 3.78 4.140 0.691 1.074 1.341 1.753 2.131 2 249 2.602 2.947 3.286 3.733 4.073 15 1.746 4.015 (b) If x =77.5 and s =5.8, compute the test statistic. 16 2 235 2.92 2.110 2.898 0.688 0.862 2 214 2.878 3.610 3.922 The test statistic is * = ]. (Round to two decimal places as needed.) 0.688 2.093 2 205 3.174 1.064 2.528 2.845 3.850 0.686 1.0613 1.323 1.721 2.080 2.189 2518 2.831 3.135 3.527 3.819 0.858 3.119 3.505 3.792 0.858 (c) Approximate the P-value. Choose the correct answer below. 0.857 1.059 1.318 1.711 2.064 2.172 2.79 3.745 0.684 1 058 1.316 1.708 2.787 1.315 2.779 3.707 O A. P-value
